Apologies, I did not expect a reply so quickly.
When the washing machine hits fault state, its a constant single beeping.
There are eight lights along the top right, when it hits fault state, the light sequence from the left, is as follows:-
lights 3 and 5 are lit green, light 7 is orange, light 8 is red, the rest are unlit.
side note- I can advance the cycle to final spin to rid washer of water.
